I can help you update your timesheet payroll settings, nshiers1-maine-r.
You have the option to enter hours when you create paychecks instead of copying the hours from the employee's timesheets. Let me show you how to edit the payroll settings:
Log in to QuickBooks Online.
At the upper-right, click the Gear icon and select Payroll settings.
Under the Employees column, select Time Sheets.
You can change the selection to I'll enter hours when I create paychecks.
Then, click OK.
Every time, you create a timesheet the total billable hours entered will only show on the invoice. Aside from that, it won't automatically sync every time you run the payroll of your employees.
